Answer :
To calculate the number of board feet needed to cover a 12x20 floor with 3/4" plywood, you can use the following formula: (Length * Width * Thickness) / 12.
To calculate the number of board feet needed to cover a floor, you need to consider the dimensions of the floor and the thickness of the plywood. In this case, the dimensions of the floor are 12 feet by 20 feet, and the thickness of the plywood is 3/4 inches.
To calculate the number of board feet, you can use the formula: (Length * Width * Thickness) / 12.
First, convert the dimensions to the same unit. Since the thickness is given in inches, we'll convert the length and width to inches as well. Multiplying the length (12 feet) by 12 gives us 144 inches, and multiplying the width (20 feet) by 12 gives us 240 inches.
Next, plug in the values into the formula:[tex](144 * 240 * 3/4) / 12[/tex].
Multiply the length, width, and thickness together: 103,680 cubic inches. Then divide by 12 to convert to board feet: 8,640 board feet.
Therefore, you will need 8,640 board feet of plywood to cover a 12x20 floor with 3/4" plywood.
